Presentation control device, information presentation system, presentation control method, and storage medium storing presentation control program

Abstract

A presentation control device includes a risk calculation unit to acquire input information indicating situations where a group of object persons in a monitoring region is placed, and to calculate a risk level; a notification determination unit to determine presentation contents indicating contents of a warning, a presentation method, and the group of the object persons, based on the risk level of each of the object persons; a presentation control unit to make a presentation device determined based on the presentation method and the group present the presentation contents; and a response acquisition unit to acquire responsive action information indicating actions of the group immediately after the presentation of the presentation contents from a responsive action detector detecting actions of the object persons in the monitoring region, wherein the notification determination unit updates the presentation contents, the presentation method, the group, and presentation device, based on the responsive action information.

What is claimed is: 
     
         1 . A presentation control device comprising:
 processing circuitry   to acquire input information indicating situations where a group of object persons in a monitoring region is placed, and to calculate a risk level representing a degree of dangerousness of a situation where each of the object persons is placed based on the input information;   to determine presentation contents indicating contents of a warning to the group, a presentation method indicating a method of the warning to the group, and the group of the object persons who should be notified of the warning, based on the risk level of each of the object persons;   to make a presentation device determined based on the presentation method and the group present the presentation contents; and   to acquire information indicating actions of the group immediately after the presentation of the presentation contents, as responsive action information, from a responsive action detector detecting actions of the object persons in the monitoring region,   wherein the processing circuitry updates the presentation contents, the presentation method, the group, and presentation device, based on the responsive action information.   
     
     
         2 . The presentation control device according to  claim 1 , wherein the processing circuitry calculates the risk level based on the input information which includes one or more items of
 information out of video information outputted from a monitoring camera,   detection information outputted from an object sensor, staff input information outputted from an operation panel operated by a staff,   environment information outputted from an environment monitoring device, and   information transmitted from a mobile terminal.   
     
     
         3 . The presentation control device according to  claim 1 , wherein the processing circuitry
 acquires a plurality of items of the input information, and   determines the risk level based on the plurality of items of input information and reliability depending on types of the plurality of items of input information.   
     
     
         4 . The presentation control device according to  claim 1 , wherein when the responsive action information includes a situation requiring predetermined preferential handling, the processing circuitry makes emphasized presentation of warning information and a request for dispatch of a staff member. 
     
     
         5 . The presentation control device according to  claim 1 , wherein the processing circuitry changes the presentation method from presentation of a visual warning to presentation of an auditory warning or from presentation of an auditory warning to presentation of a visual warning, based on the responsive action information. 
     
     
         6 . The presentation control device according to  claim 1 , wherein the processing circuitry judges presence or absence of an input requesting emergency handling and when there is a request for the emergency handling, an emergency handling request is transmitted to a device operated by a staff member in regard to the monitoring region. 
     
     
         7 . An information presentation system comprising:
 the presentation control device according to  claim 1 ;   a situation input device to provide the input information to the presentation control device;   the presentation device; and   the responsive action detector.   
     
     
         8 . A presentation control method to be executed by a presentation control device, comprising:
 acquiring input information indicating situations where a group of object persons in a monitoring region is placed, and to calculate a risk level representing a degree of dangerousness of a situation where each of the object persons is placed based on the input information;   determining presentation contents indicating contents of a warning to the group, a presentation method indicating a method of the warning to the group, and the group of the object persons who should be notified of the warning, based on the risk level of each of the object persons;   making a presentation device determined based on the presentation method and the group present the presentation contents;   acquiring information indicating actions of the group immediately after the presentation of the presentation contents, as responsive action information, from a responsive action detector detecting actions of the object persons in the monitoring region; and   updating the presentation contents, the presentation method, the group, and presentation device, based on the responsive action information.   
     
     
         9 . A non-transitory computer-readable storage medium storing a presentation control program that causes a computer to execute:
 acquiring input information indicating situations where a group of object persons in a monitoring region is placed, and to calculate a risk level representing a degree of dangerousness of a situation where each of the object persons is placed based on the input information;   determining presentation contents indicating contents of a warning to the group, a presentation method indicating a method of the warning to the group, and the group of the object persons who should be notified of the warning, based on the risk level of each of the object persons;   making a presentation device determined based on the presentation method and the group present the presentation contents;   acquiring information indicating actions of the group immediately after the presentation of the presentation contents, as responsive action information, from a responsive action detector detecting actions of the object persons in the monitoring region; and   updating the presentation contents, the presentation method, the group, and presentation device, based on the responsive action information.
